Transcript of Nuclear Energy
Ryan Canter Nuclear Energy 1. Lots of Uranium 2. Reduces dependency on fossil fuels 3. Problems are rare 4. Negative feedback mechanism prevents meltdown 5. Minimal CO2 emissions 6. Highly Efficient 1. Costly to build 2. High Risk transportation 3. Can be used for weaponry 5. Disposal of waste is unsafe and costly 4. Accidents cause extreme negative consequences So if there is a radiation leak, we will get this.... right...? March 11, 2011: Fukushima Daiichi Nuclear Power Station 1. Massive earthquake damaged breakers and emergency generators were necessary 2. Large tsunamis flooded emergency generators 3. Energy loss to the units prevented the water from cooling the reactors 4. Damaged reactors exploded 5. Radioactive material forced evacuation 1. Future reactors will be safer and more affordable 2. Further innovation may reduce radioactive waste 3. Thorium may replace weapons grade uranium Strategic Defense Initiative 1983 4. Nuclear fusion even safer energy source 5. Fission is useful for space exploration Fission Fusion 1. Splitting of atoms 1. Joining atoms to make a larger atom 2. Energy released is lower than that released by fusion 2. Energy released 3-4 times higher than fission 3. Does not take much energy to get started 3. Takes more energy to get started than fission 4. Produces more radioactive material 4. Produces less radioactive material 5. Hydrogen bomb 5. Atomic bomb
